SparkFun OpenLog ArtemisThe SparkFun OpenLog Artemis is an open source data logger that comes preprogrammed to automatically log IMU, GPS, serial data, and various pressure, humidity, and distance sensors. All without writing a single line of code! OpenLog Artemis, or "OLA," automatically detects, configures, and logs Qwiic sensors. The OLA is specifically designed for users who just need to capture a lot of data to a CSV and get back to their larger project.

The OLA is specifically designed for users who just need to capture a lot of data to a CSV and get back to their larger project.

&feature=emb_title

Included on every OpenLog Artemis is an IMU for built-in logging of triple-axis accelerometer, gyro, and magnetometer. Whereas the original 9DOF Razor used the old MPU-9250, the OpenLog Artemis uses the latest ICM-20948 from InvenSense capable of nearly 250Hz logging of all nine axes. Simply power up the OpenLog Artemis and all incoming serial data is automatically recorded to a log file with baud rates up to 921600bps, supported! The OLA also has four ADC channels available on the edge of the board. Voltages up to 2V can be logged with 14-bit precision up to 1900Hz for one channel and 1000Hz logging all four channels. Additionally, based on feedback from users we've added an on-board RTC so that all data can be time stamped.

The OpenLog Artemis is highly configurable over an easy to use serial interface. Simply plug in a USB-C cable and open a terminal at 115200bps. The logging output is automatically streamed to both the terminal and the microSD. Pressing any key will open the configuration menu.

The OpenLog Artemis automatically scans, detects, configures, and logs various Qwiic sensors plugged into the board (No soldering! No programming!). So see the latest list of auto detect supported modules, please see the Sparkfun website.

This OpenLog uses common microSD cards to record clear text, comma separated files. You probably already have a microSD card laying around but if you need any additional units see the related items below. The OpenLog Artemis supports microSD cards formatted as FAT32 as well as the older FAT16 formats up to 32GB. Currently, the OpenLog Artemis does not support microSD cards formatted with exFAT but we plan to offer support for it in the future

Very low power logging is supported. OpenLog Artemis can be configured to take readings at 500 times a second, or as slow as 1 reading every 24 hours. You choose! When there is more than 2 seconds between readings OLA will automatically power down itself and the sensors on the bus resulting in a sleep current of approximately 18uA. This means a normal 2Ah battery will enable logging for more than 4,000 days! OpenLog Artemis has built-in LiPo charging set at 450mA/hr.

New features are constantly being added so we've released an easy to use firmware upgrade tool. No need to install Arduino or a bunch of libraries, simply open the Artemis Firmware Upload GUI , load the latest OLA firmware, and add features to OpenLog Artemis as they come out!

The OLA can be tailored to many different applications and we will be releasing custom versions of the firmware which can be found in the documents section below.

Perfect! Read this for large size
Special Size Type: Standard, Size: Large, Color: (New) Rinse
Man, let me tell you when I say I've never been so nervous about an amazon order before. I've wanted one of these for a long time but the reviews had me a little shook. I'm 6' tall and 210lbs. I'm definitely not fat but I do have a bit of a beer belly, the rest of me is pretty lean and muscular. I measured my chest at 44" while wearing a light hoodie. The size chart said I should be a large and so that's what I ordered. It fits perfectly, I can honestly say an XL would probably be too big. The large is not too tight, not too loose. I have plenty of room in my shoulders, and I can wear a flannel shirt and hoodie under it and button it closed comfortably. The arms are the perfect length for me as well, falling just past the wrist. I read a few reviews about the quality of the denim, I got the rinse color (dark wash) and it feels plenty high quality to me. No issues that I can see with the pockets, buttons, or stitching anywhere. I did however get a blank red tag on the front pocket which concerned me, I looked that up and apparently Levi manufacturers 10% of their products with blank red tags instead of saying "Levi" and supposedly that makes them more valuable because of the rarity? Whatever, I don't care about that as long as it's not a knockoff. I plan to wear this for a long time so the resell value is of little importance to me anyways. Even if it was a knockoff, I'd probably keep it anyways because of how good it looks. Overall I'm pretty happy with this purchase and would recommend.

“This Jacket Changed My Life, My Posture, and Possibly My Destiny.”
Special Size Type: Standard, Size: X-Large, Color: Colusa/Stretch
“This Jacket Changed My Life, My Posture, and Possibly My Destiny.” I bought this Levi’s Men’s Trucker Jacket on Black Friday for 50% off, and honestly, I think the universe has been waiting for this moment. The second I slipped it on, I felt the air shift — like somewhere, a tumbleweed rolled across a Walmart parking lot in respect. This jacket didn’t just fit. It claimed me. Suddenly, I walked differently. Not better — just with more narrative significance. Like I was the mysterious side character in a Netflix show who only appears to give life-changing advice next to a jukebox. People look at me now like I’ve been to places. Seen things. Done questionable but noble acts on the open road. What This Jacket Made Me Believe About Myself: That I could fix a motorcycle using only pliers and emotional willpower That I should own sunglasses even indoors That I absolutely should lean against things while staring into the distance That I have opinions about blues music That someone, somewhere, owes me money My confidence skyrocketed. My responsibilities? Stayed exactly the same — but I now ignore them with swagger. The Black Friday Factor Getting it 50% off activated a new primal ego inside me. Every time someone compliments it, I immediately shout: “THANKS — GOT IT HALF OFF!” Even when they weren’t complimenting it. Even when they weren’t talking to me. Even when I was alone. Durability This thing could survive: A bar fight A mild tornado Being run over by a shopping cart stampede The emotional collapse of a man who just realized he peaked in high school It’s rugged. It’s iconic. It smells faintly of “I could do better, but I won’t.” Side Effects (documented): Strangers nod at me Kids think I know how to play guitar I feel obligated to say things like “Let’s ride” even when entering a minivan My reflection winked at me once Final Verdict This isn’t just a jacket. It’s a lifestyle upgrade. A fabric-based personality transplant. A denim prophecy fulfilled. Five stars. If Levi’s ever discontinues this jacket, I will chain myself to their headquarters and demand justice.

Vintage 60's cool, but sizing is a difficult decision
I can't believe I haven't owned one of these for the last 40 years or so. To put one on after all these years takes one right back to the questionable days of one's youth when you wore these bare chested underneath while tooling around on your Kawasaki 500 triple. Well it will take you back if you haven't let yourself go too far! I received both a large and a medium in black (love the free returns on clothing, I always order two sizes so I get the right fit). They are both made in Mexico and look very neat and well made, the denim is on the thin side but OK for warm weather. Nowhere is there any tag saying shrink to fit or shrinks two sizes. The tag says machine wash cold, tumble dry medium. The large is quite large on me (I'm 5'9" 168 lbs trim and athletic build, more often than not I wear large in T shirts and jackets), the sleeves are way too long and loose, body too long and loose. Would have to shrink drastically to fit me, I really doubt it would shrink anywhere near that much. This type jacket is just all wrong if it's too loose fitting, witness the BLACK color one in the model photos, just not too cool. The medium fits much much smaller but IMHO perfect for this style jacket, a classic fit like Steve McQueen or Robert Plant would have sported, high waist and tight shoulders with sleeves rolled back a little. If you look at the model in the 'HARRINGTON' color you have the idea. It will be totally bitchen on today's big black BMW oilhead. This is the youthful fit I was looking for but any shrinkage would be too much. I am conflicted because I would like to wash this jacket and break it in, put a little wear and tear on it. But I wouldn't dare dry it with heat. I might try washing it in cold water and then line dry or I may just dry clean it. I am tempted to go out and drag it up and down the gravel driveway and run it over with my truck a few times till it acquires some of the same attitude it inspires in me. All I need now is a Psychedelic soundtrack and I'm all set to relive the glory days, better than the first time around. A little research on the Levi's website reveals they have a regular fit and a slim fit in addition to this relaxed fit which is the only one available on Amazon. I find that this relaxed version works well in the medium size anyway, it seems to be relaxed only in the body, not so much in shoulders or sleeves.

Fit True to Size
Special Size Type: Standard, Size: Medium, Color: (New) in the Sandbox
Good quality you'd expect from Levis. Fit on the very slightly snug size of true to size. Very nice jacket.

Large fits well, comfortable, though a bit more flex to it than expected
Special Size Type: Standard, Size: Large, Color: Colusa/Stretch
Very nice, though it is stretchier than expected. I purchased a large. The fit is good for me at 5'11" / 200lb, average build. My shoulders are a bit broader than most and the fit is maybe just a weeeeee bit tight, under the arm when reaching for something. The arm length and overall length are both great. This will be a mid-season jacket so I do not plan to wear a hoody or other bulky item under it. It would work, but I think a bit too snug for me. I reccomend washing it immeidately then taking a hot iron with steam to the pockets and collar which I feared were trying to start and curl up. They need to be trained early! I am more pleased than expected.
